More.\partio i1larly, itllis a primary object of thegpresentlinventiontoprovide a post puller of extremely simple construction capable of being utilized for pu-lling posts (of various sizes and shapes from the vground or which .may be em ployedfor'lifting and supporting a post in an elevated position preparatory to positioning it in a vpost hole.

Stillaurther object of lthefinvention is to provide a-combination tool or machine for the aforeiescribedpurposes of extremelyssimple construction, capable of being economically manufacturedgand sold and which will.. be'lextremelyfdurable and ,.e'fcient for its intended-purposes.

'ariousother objects and @advantages rfo'f @the invention will'hereinafter become more fully apparent from the following description of the drawings, illustrating preferred embodiments thereof, and wherein:

Figure 1 is a side elevational view showing the device in an applied position and being employed as a post puller;

Figure 2 is an elevational view of the device looking from left to right of Figure 1 and with the post omitted therefrom;

Figure 3 is a top plan view of Figure 1;

Figure 4 is a View similar to Figure 1 but showing the implement employed as a lifting jack;

Figure 5 is a View similar to Figure 1 showing the implement employed as a post puller for posts of small cross sectional size, and n Figure 6 is an enlarged fragmentary perspective view of the upper portion of the implement.

Referring more specifically to the drawings, the combination post puller and jack, designated generally 8, includes an upright supporting standard 9 mounted at its lower end in a base I0 which is adapted to rest on any suitable supporting surface. A lever II is pivotally connected near one end thereof by a nut and bolt fastening I2 to the standard 9, adjacent the upper end of the latter. The lever II includes an elongated handle portion I3 having a pair of strap members I4 secured to opposite sides of one end thereof by fastenin'gs I5 -and having ends projecting therefrom to provide a bifurcated extension of the handle I3 which straddles the standard 9 and through which the fastening I2 extends.

A substantially U-shaped clevis I6 is pivotally 'J1 Tenum'. (classe-e132) i it.)

Assuming that it is desired to utilize the implement 8 for pulling a post 25, as seen in Figures 1 and 3, of relatively large diameter, the implement is set up with the base I0 resting on the ground in close proximity to the post and after the clevis I6 has been applied over the upper end of the post and so that the post is disposed therein in the opening thereof formed by the bite portion of the clevis and the adjacent edge of the web I8.

With the collar or ring 20 supported in an elevated, inoperative position by the clip 23, the handle end I3 of the lever II is swung upwardly from its full line to or beyond its dotted line position of Figure 1 for causing the clevis I6` to slide downwardly on the post 25 and to pivot on the fastenings I'I relatively to the lever II in accomplishing this sliding movement. When a downward pull is subsequently exerted on the handle end I3 of the lever II, the outer edge of the web I8 will be caused to bite into the post 25 to thereby clamp the post between said edge and the bight portion of the clevis I6 as the clevis is rocked on its pivot I1 relatively to the lever II until it is in binding engagement with the post. Further downward swinging movement of the handle I3 will cause the clevis I6 to be elevated and to lift the post 23 out of the hole in which it is embedded. Ordinarily a single stroke of the lever II is suflicient to completely extract the post 25 but if necessary,the lever II may be again rocked counterclockwise for reengaging the clevis I6 at a lower point on the post 25 and so that the lifting operation can be repeated. After the post 25 has been lifted out of the ground, if desired, it may be supported in an elevated position by releasing the collar 20 from the clip 23 and allowing it to slide downwardly on the standard 9 until it assumes a canted position, as illustrated in Figure 4 so that by binding engagement with the standard it will anchor the exible member 2I thereto for preventing the lever clockwise -and so that the implement 8 will thus function for supporting the post in an elevated position.

Where it is desired to similarly utilize the device for lifting and extracting a post of small diameter, as seen at 26 in Figure 5, the implement 8 is similarly applied to the post except that the upper end of the post 26 is received II from swinging counter-v Various modifications and changs are c'n`- templated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter dened by the appended claim.

We claim as our invention:

'An implement of the character described comprising a base adapted to rest on a supporting surface, a standard xed to and rising therefrom, a lever fulcrumed adjacent one of its ends on said standard, a clevis pivotally connected at the terminal of its legs directly to the shorter end of said lever for slidably engaging a post to be pulled when said lever end is swung do-'wnwardly, and a web extending between the legs of the clevis and spaced from the bight portion through the opening I9 of the web I8 and after r the lever I I has been rocked lcounterclock'wise to lower the clevis on the post 26, by rocking the l lever in the opposite or clockwise direction, clevis I6 will pivot on the fastening I1 relatively tothe lever for binding engagement with the post 26 and so that further clockwise movement of the lever II will lift the post in the same manner as previously described with respect to the post 25. For extracting posts of large diameter or for elevating a load, as indicated at 21 in Figure 4, a exible member or chain 28 is provided at each end thereof with a hook 29, o-ne of which hooks is engaged with the clevis I6 and the other of which hooks is engaged with a link of the chain to form a loop 38 around the load 21 or around the base of an embedded post sothat when the lever II is rocked in a clockwise direction the load will be lifted or the post extracted and the collar 28 may be employed for holding the lever against counterclockwise swinging movement on its fulcrum I2 for supporting the load or post 21 in an elevated position.
